GWD-9-Q38:

In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.

Which of the following, if true, most strongly supports the argument against Moviemania’s claim?

A.    Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.

B.    Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.

C.    Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.

D.    Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.

E.     The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.

这道题为什么选A而不选C呢？我觉得C不是更能直接表明sales增长的原因吗？谢谢！！

LZ仔细看题目去年， M把coconut oil 换成了canola oil， 现在打算换回去， 因为M说hurt sales

结论说， M是错的，因为数据表明， M销售上升了5%

问加强， 这里加强的是销售上升，而不是加强M的言论

A说所有refreshments销售上升少于5%，根据题目说，爆米花上升5%，那么说明爆米花上升的比一般refreshment快， 加强结论， 说明销售上升

C说顾客喜欢coconet oil，如果顾客喜欢coconut oil，那么应该销售下降才对，削弱结论。。。

我觉得可能是楼主没有看清题目的加强究竟是加强谁。。。所以才会误选

但是...

the argument against Moviemania’s claim 是 That claim is false since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year

如果这个argument本身就是正确的，就是说popcorn sales increased, 没有被hurt, 那么Moviemania's claim就已经被充分否决，题中任何一个选项都是不需要的，不是吗？A说total sales 怎样怎样根本是多余的。

I seriously doubt the validity of this question! 请NN们指教！多谢。

不对, "这个argument本身就是正确的" 这个说法根据在哪里?

事实上这个argument本身还不算太充分，需要support. 因为单从popcorn sales increased 不能说明没有被hurt. 现在popcorn sales increased 5%, 它如果没有被hurt也可能会增加10%或者更多. 比如说由于人们生活水平提高, sales普遍提高了20%, 而popcorn才5%, 当然是被hurt了!

所以我们需要一个support, 说明和其他的东西比, 5%就已经很好了, 能充分说明没有被hurt
